Are QR Codes Dangerous?



Are QR Codes Dangerous?

QR codes are popping up almost everywhere these days. From advertisements on TV to billboards and magazine ads, signboards, and even print magazines. QR codes are being used as a mass communication tool by brands to reach out to consumers, boost sales of their products and increase brand loyalty. Are they (QR codes) dangerous?

What Are QR Codes?

QR codes are squares of black-and-white patterned code, usually found on print ads or billboards. They can also be small enough to appear in the corner of a product label. When you scan one with your phone’s camera, it links to a website or app that provides more information about whatever you’re looking at. In this way, QR codes act like miniature billboards for brands—and just like regular billboards, they often contain hidden messages that are only visible when scanned by your phone camera.

How Are QR Codes Utilized?

QR codes are everywhere. You may have seen them in stores, magazines, or even on your phone. But do you know what they mean?

You can use QR codes (Quick Response Codes) for various purposes, including sharing links, providing marketing information, and providing a location. In China, QR codes are used as a form of payment by scanning the code with your phone to complete transactions at places like subway terminals and convenience stores. They’re also often used in hospitals to verify patient information and other medical information between patients, doctors, and hospitals.

Museums help provide extra information about exhibits; when you scan one, it will tell you where that piece of art is located within the museum and give more details about its history or significance to the period you made it during!

It’s easy to link a QR code to a malicious website.

You could use a QR code scanner to scan for malicious links.

Make sure the QR scanner is trustworthy, though! If the link is malicious, it can lead to severe issues.

Attackers can exploit them in numerous ways.

QR codes can be dangerous because they are easy to copy and use, allowing attackers to access your data. This can lead to a variety of cybercrimes and scams, such as:

  • Malware: Attackers can use a QR code on an infected website or email attachment when you try to open it. If you scan the QR code with your phone camera, the malware will infect your device.
  • Phishing: Hackers will post fake apps in app stores, which look legitimate but are created by hackers, so that customer information is stolen from them (usually credit card numbers). The hacker then uses this information for identity theft or other malicious activities.
  • Data theft: If someone scans your QR code without permission or steals it from your device — say they pick up the phone while you’re using it — they have access to all the sensitive data stored on the device.

The Resulting Compromise Can Be Devastating if a QR Code is Linked to a Malicious Website

QR codes are a type of barcode that smartphones can scan. They were initially developed in Japan but have since spread to the rest of the world. The fact that they’re so easily converted into a link makes them inherently dangerous—and that’s why you should take precautions to protect yourself from them.

The most common way QR codes are hacked is through “man-in-the-middle” attacks, which involve inserting malicious code into a seemingly innocuous image file (like an animated GIF). If someone downloads this image and views it on their phone, their device will try to access whatever web address is encoded in that picture automatically; if someone else has already inserted malicious code there, then they’ll be able to steal any information or login credentials used on the user’s phone next time they use it!

If you see a friend post something like this on Facebook or Twitter—or even if you find one yourself somewhere online—you should never click any links embedded within it unless you first verify what kind of content they lead to with another source (like Google Images). Otherwise

The Good News is that You Can Avoid QR Code Security Issues with the Right Approach.

The good news is that you can avoid QR code security issues with the right approach. For example, make sure you have a good antivirus app installed on your phone and check the reputation of any app before using it to scan a QR code. Also, only use codes from trusted sources and never enter any personal information into an online QR code scanner (such as your email address). Finally, be careful when using QR codes in real life: make sure no one can see what’s being scanned because even if you’re not sharing anything sensitive with them directly, there could be hidden messages embedded within that could compromise your identity or other sensitive information about yourself or others who might be physically close by at that time.

Download a Trustworthy QR Code Scanner on Your Mobile Device

  • Download a trustworthy QR code scanner on your mobile device.
  • Use a QR code scanner updated regularly and only use QR codes from trusted sources.
  • If you don’t trust a QR code, don’t scan it!

When it Comes to QR Codes, Security Matters

As an IT professional, you should know that QR codes are beneficial and not inherently dangerous. However, it’s essential to understand the risks of using them and how to mitigate them to ensure your organization does not fall victim to a security breach. To get started, consider these common scenarios where you might use QR codes:

  • At trade shows or conferences to advertise products or services;
  • On a business card as part of your marketing efforts;
  • In emails as links to online content and offers; and
  • On printed materials as part of product packaging or instructions for use.


Ultimately, it’s not the QR code that’s dangerous. It’s how you use it—and whether or not you’re aware of its limitations. We’ve outlined some ways to protect yourself from potential harm but always remember: if something seems too good to be true, it probably is.

Yes, there are some benefits to using a QR code (like being able to access information quickly), but it can also hurt your brand if misused.

We recommend avoiding these codes altogether unless necessary because they’re not helpful and come with unnecessary risks!
